Insulated Fluekits

All imported closed-system / slow-combustion fireplaces should be installed using an insulated fluekit. These imported fireplaces radiate a tremendous amount of heat through the flue, if not insulated. This can lead to the drying out of the rafters in your roof, which could eventually lead to spontaneous combustion. As there are no laws governing the installations of imported fireplaces in South Africa, a lot of companies still sell plain, un-insulated flues to customers who rely on the salesman's supposed superior knowledge.

At Vulcan we follow the European standards of installation, and only sell stainless steel insulated fluekits that is guarenteed to protect your roof structure's integrity. Our insulation can handle up to 600º Celsius. We supply 5 standard size flue kits: (internal diameter) 125 dia, 150 (152) dia, 180 dia, 200 dia and 250 dia. This fits most imported units. However, we can custom-make if needed.

Choose between 3 different grades of stainless - 430, 304 or 316. 430 Stainless steel is a magnetic stainless that has a shiny look, while 304 & 316 Stainless has the "classic" stainless look and is non-magnetic. Known by most people as the true stainless steel, 304 and 316 are the grades we suggest to use if you are living close to the ocean's corrosive sea-air. To that effect, our endcaps are all spun from 316 stainless steel.
Also available to complete your installation, are bends, T-Pieces, Ceiling plates and brackets manufactured in the same grades of stainless steel as our flues.

  • Endcap Flue
    Endcap Flues
    Endcap flues are also insulated flues, with the added endcap that neatens the transition between single and double insulated flues. All our endcaps are manufactured using 316 stainless steel. Both inner and outer flues are manufactured using the same grade of stainless steel.
  • Insulated flue

    Also available in all sizes and grades of stainless steel. The standard and 45º T-Pieces come complete with a bowl for collecting of condensation. The T-Piece is especially convenient in making sweeping the chimney a breeze.
  • Grade 304 Y-Piece
    YES, some of us has OCD. This Y-Piece balances the look where a bend to the side is neccessary due to restrictions such as a roof beam or concrete beam. Taken only through the ceiling and into the roof cavity, the "extra" leg is blocked off to keep smoke from entering.
  • Damper Kit
    Damper Kit
